I have a 2002 Audi A4 1.8T Quattro with about 64,500 miles on it. When I bought it from the dealership, the heat came out cold. They said they flushed it and had to replace a plastic ring that had cracked and was letting air into the hose. I only used the heat for a few weeks because winter was about over. Now, 9 months later, it's coming out cold again and the dealership says it needs a new heater core. What can I do to test that it's definitely the heater core? If I need a new one, how do I replace it? Thanks.
